Velocity-Gradient Probability Distribution Functions in a Lagrangian Model of Turbulence

The Recent Fluid Deformation Closure (RFDC) model of lagrangian turbulence is recast in path-integral language within the framework of the Martin-Siggia-Rose functional formalism. In order to derive analytical expressions for the velocity-gradient probability distribution functions (vgPDFs), we carry out noise renormalization in the low...

Three-dimensional measurements of heavy and light particle dispersion in shear turbulence

We present new experimental data concerning the statistics of heavy and light particles dispersed at low concentrations in a homogeneous turbulent shear flow. Information on both the spatial distribution and on the relative velocity of the dispersed phases is obtained by accurate three-dimensional optical measurements, and will allow to...

High resolution simulations of random fields and implications on stochastic modelling of turbulence

We study through high resolution numerical simulations unknown features of a random velocity field based on the so-called multiplicative chaos, previously proposed in the literature to model turbulence. We investigate the influence of the intermittency parameter, observing the behaviour of the field as it is changed. In this way, we can...

Why is it so hard to say sorry? (abstract)

When making a mistake, individuals are willing to apologize to secure further cooperation, even if the apology is costly. Similarly, individuals arrange commitments to guarantee that an action such as a cooperative one is in the others’ best interest, and thus will be carried out to avoid eventual penalties for commitment failure. Hence, both...

Sustainability evaluation of graduate courses in an university of the South of Brazil

The Auditing Instrument for Sustainability in Higher Education (AISHE) is an assessment instrument developed specifically for higher education. The AISHE had been applied in many institutions in its first version (AISHE 1.0) and has a new version the AISHE 2.0, with new elements for evaluation (ROORDA, 2008). This paper shows the results of...

Devising ecodesign strategies in a furniture industry based on cluster analysis

This study aims to devise group guidelines to implement ecodesign practices (Design for Environment) in the furniture industry. Surveys were the main research method used to investigate the level of application of ecodesign in 22 companies in southern Brazil. The term ecodesign was unfolded into ecodesign practices (set of activities), which...

The Latin America meeting of sustainable universities (I Elaus): Results and possibilities

Higher Education Institutions (HEI) play an important role in sustainable development with their education, research and developed extension activities on environmental practices. With the purpose of organizing an event focused on the argument for education for sustainable development within Latin America and to initiate a process of...
